Stackexchange fucking sucks

Can we talk about why stackexchange sucks and share some fucking alternatives?

* tons of useful questions closed because "primarily opnion-based" or some other garbage flagging shit
* rulecucks everywhere fagging up the place
* can't even do absolutely basic shit until you earn some internet points
* entire site revolves around fake internet points
* everyone is fucking hostile all the time protecting their internet points

God damn it, I'm sick of this industry. What are some alternatives to this cancer?

Should I care about stackexchange, github and other such sites?
I read some threads when I have questions that books can't answer, but I never actually post. I've read that a lot of people use these sites for networking, how's that? I'm only interested in research, academia, and having a job 10 years from now; so I shouldn't have to show off my knowledge and contribute to projects I don't care about just to make contacts, right?
